VAPOR -LAM P.

SPECIFICATION forming part of Letters Patent No. 410,407, datedSeptember 3, 1889.

Serial No. 277,554. (No model.)

To all whom it may concern:

Be it known that I, PETER J. FITZGERALD, a citizen of the United States,residing at Sharon Hill, in the county of Delaware, State ofPennsylvania, have invented a new and useful Improvement in Vapor-Lamps,which improvement is fully set forth in the following specification andaccompanying drawings.

My invention consists of avapor-lamp having means for convenientlysupplying the reservoir thereof with hydrocarbon or otherilluminating-fluid.

It also consists of means for preventing volatilization of the fluid andescape of the same from the reservoir, due to the action of the heat ofthe sun thereon.

.Figure 1 represents a partial side elevation and partial verticalsection of a vapor-lamp embodying my invention. Fig. 2 represents a Viewof a detached portion thereof.

Similar letters of reference indicate corresponding parts in both gures.

Referring to the drawings, A represents a lantern, which is supported onthe post B, the latter being hollowr and closed on all sides exceptingat the top. The lower portion forms a chamber B for containing oil orhydrocarbon fluid, or may have a separate chamber for said purpose.Within the post is a pipe C, which passes through the top thereof, andis connected by a branch D with the reservoir E, the latter beingsustained on the lantern. Connected with the branch D is a supplypipeE', leading to the burner F, said pipe having a plug or cock G forregulating the supply of fluid to the burner. The branch D is providedwith a two-way cock Il for controlling the supply of fluid from the pipeC to the reservoir E. Connected with the chamber B is a pipe .I whichleads from atank K, the latter being located in the ground or elsewhereand containing hydrocarbon fluid under pressure, the pressure beingproduced by means of a pump or other suitable apparatus or means. Thepipe J, it will be noticed, enters the chamber B above the opening inthe lower end of the pipe O, and the said opening is near the bottom ofthe chamber. By this construction impurities which have passed into thechamberB through the said pipe .I do not pass into the pipe C unless theoil in the other advantage of the said chamber B is that it aids insecuring a more uniform flow of oil in the pipe C. It will be seen thatwhen the cock H is opened the iiuid from the tank is forced into thechamber B and from thence through the pipe C and branchD into thereservoir E. Vhen the latter is filled, the cock His turned, wherebycommunication With the pipe C is closed and communication with the pipeE opened, so that the fluid enters said pipe E and may be directed tothe burner when the cock G is opened.

The reservoir E is covered or jacketed with asbestus, whereby saidreservoir is prevented from becoming materially heated during theday-time while exposed to the sun, and thus volatilization of the fluidcontained in the reservoir and consequent escape of the vapor at thejoint of the supply cap or cover of said reservoir are prevented.

I am aware that it is not new to place a water-jacket above thereservoir of the lamp to protect the contents of the same from the heatof the ame, but with such it is necessary to provide a basin or otherdevice to contain the said Wat-er; but in the invention herein set forththe asbestus is placed upon the top of the reservoir, and, owing to itsadhesive qualities, remains thereon without mechanical devices beingrequired.

The matter described and shown herein relating to the burner proper isreserved, being made the subject of another application, filed June l5,1889, and bearing Serial No. 314,437.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The pipe C, connected with the reservoir E, a place of supply offluid under pressure, and a chamber connected therewith, the branch D,with the cock H, and the pipe E', with the cock G, combined andoperating substantially as described.

2. A supply-tank adapted to contain liquid under pressure, a chamberconnected by a pipe with said supply-tank, a supply-pipe leading fromsaid chamber and havinga two-way cock therein, a reservoir connectedwith said supply-pipe, and a pipe leading from said cock and having acock and burner, said parts being combined substantially as described.

chamber is lower than the said opening. An

3. The tank K, adapted to contain liquid IOO under pressure, a chamberconnected with said tank, the pipe C, leading from said chamber andhaving the branch pipe D, with the two-WayI cock therein, the reservoirE, communicating with the said branch pipe D, and the pipe E,With cock Hand burner F, said parts being`combined substantially as described.

4. The tank K,in combination with a separate chamber, the post B, thepipe C, leading from said chamber and to said post, the branch pipe D,having the cock H, the reservoir E, supported by a frame connectedWiththe post B, and the pipe E', leading from the two-Way cock H andprovided with the cock Gr and burner F, said parts being combined substantially as and for the purpose described. 5. A lamp with a reservoirabove the ame of the same, the said reservoir having a coating ofasbestus on the upper surface thereof, substantially as and .for thepurpose set forth.
